Thank you for putting up this forum its awsome !! Sorry for not posting more info on my truck. I have an '03 (manufactured date 05/03) it has 112k miles 4x4. My PROBLEM is The indicator shows the circle around P and N but it does'nt show up when I put it in R D321 but you can feel the trans go on gear . I've replaced govenor pressure sensor and silenoid, fluid, filter then took it to the local dealership and they put it on a hand held computer and said the PCM was not responding at all so he unpluged a couple of sensors and plugged them back in and still no response to his computer so I replaced the PCM and it still doing the same thing. So I'm lost is there a seperate comp for the trans or is it possible the gage cluster is not sending the messasge that its in gear ? Thank you all for the info!!! --- Update to the previous post... How do I fill out my signature ? I would be happy to put it on here but I don't know where to add that info.

To whom that might be able to help. My Problem is the trans is not talking to the pcm (I think), When I put it in gear the trans shifts into gear but will not shift to any other gear, the indicator (PRND321) the circle around the gear is not showing up, its there when in (P)and (N) but when I put it in gear it doesnt show up ??????????Any info will be GREATLY APPRECIATED !!! I did have dealer ship scan and they said that the pcm was not registering , as if its not in the truck.:banghead:
